Description of the intervention
The use of image guidance is widely set as an important tool for managing diseases of the nose and paranasal sinuses by increasing surgeons’ confidence and confirming anatomic locations in challenging fields.12
The Image Guided Surgery (IGS) systems have the following items: a computer, video monitor, tracking system, surgical instrumentation, and data transfer hardware. The tracking system allows for the real-time determination of the instrument location relative to anatomical landmarks. Electromagnetic or optical tracking technology can be used to perform this position determination in the operating field against preoperative imaging data sets.3,20
